Decide the home redirect per request instead of querying at import time,
replace the removed _get_placeholder helper, stop shadowing the
is_superuser field, and set the seeded home page as the CMS home.
Use MIDDLEWARE with adapted old-style middleware, the template context
processors, explicit bootstrap3 URLs, the captcha app name, and drop the
obsolete migration module overrides and removed apps.
Adds Cache-Control: no-store and an X-Dev-Site header to the dev site
switcher so a browser cannot reuse another site's page or redirect, and
the selected site is visible in dev tools.
Each site gets a home page and four child pages, and there are twelve
dummy customers. The dummy admin password is now fixed through
DUMMY_ADMIN_PASSWORD. --purge removes all of it.
The cookie is shared by all tabs and redirects dropped ?site=, so opening
several sites made them all show the last one. The site is now taken from
<domain>.<anything> hosts (each site its own origin), with ?site= and the
cookie as fallback, and redirects keep ?site=. /dev-sites/ links use the
per-site hostnames, via sslip.io when accessed by IP.
The seed_dummy_data command creates one CMS page per site and a dummy
admin and customer, idempotently. --purge removes exactly what it
created. It runs on start when SEED_DUMMY_DATA=True and a failure does
not stop the web server.
With DEBUG on, ?site=<domain> selects the site without DNS or hosts
entries and is remembered in a cookie. /dev-sites/ lists all
configured sites as links.
